 I am worried that randomly adding/removing/changing fields in the .yamloo
 OONI test report files is going to break report parsers in horrible ways.
 And YAML doesn't have the safest track history for its parsers either.

 Perhaps we could have something like [https://developers.google.com
 /protocol-buffers/docs/overview Protobufs] for guaranteed
 marshaling/unmarshaling/parsing of report data? Setting up Protobufs for
 the reports would establish requirements, for example, that field names
 and data types/representations can't just randomly change in the future,
 at least not without bumping up the version for the report Protobuf (and
 thus regenerating the parsers/marshalers) and maintaining backwards-
 compatibility.
